In the opening minutes of every episode of Supergirl, Kara dictates her story from the doomed planet of Krypton and her journey to Earth. Her parents planned for her and her infant cousin, Kal-El, to land on Earth and allow her the opportunity to watch over him; however, Kara’s ship was knocked off course and by the time that she arrived on our world, Kal was already an adult, and already Superman.
With all that in mind, TVLine reports that the series is looking to cast a 13-year-old actor with “future leading man looks” for the role of Kal-El in a series of flashbacks set to establish his bond with Kara. The problem, of course, is that in the context of the series, Kara was trapped in The Phantom Zone when Kal was 13-years old. Though anything is possible in a show about people that fly around and have heat vision. Check back here for more details on the casting as we learn them.
Melissa Benoist leads the cast of Supergirl season one as the title character with a cast that also includes Mehcad Brooks as James Olsen, Laura Benanti as Alura Zor-El, Calista Flockhart as Cat Grant, Chyler Leigh as Alexandra “Alex” Danvers, Jeremy Jordan as Winslow “Winn” Schott, Jenna Dewan Tatum as Lucy Lane (sister of Lois), Iddo Goldberg as Red Tornado, David Harewood as Hank Henshaw, Peter Facinelli as Maxwell Lord, and Dean Cain and Helen Slater.
